Task 50
SHC Task 50

Advanced Lighting for Retrofitting Buildings

Overview

Lighting accounts for approximately 19%, i.e. 2900 TWH, of the global electric energy consumption. Projections by the IEA show that if governments only rely on current policies, global electricity use for lighting will grow to around 4250 TWh by 2030, an increase of more than 40%. Due to the world’s growing population and the increasing demand for electrically driven services in emerging economies the increase will occur despite constant improvements in energy efficiency of lighting systems. One recent study indicated that investments in energy ‐ efficient lighting is one of the most cost‐effective ways to reduce CO2 emissions.

Research and developments in the field of energy efficient lighting techniques encompassing daylighting, electric lighting and lighting controls combined with activities employing and bringing these techniques to the market can contribute significantly to reduce worldwide electricity consumptions and C02 emissions. These activities will therefore be in line with several different governmental energy efficiency and sustainability targets.

  • First results of questionnaire about methods & tools used for lighting retrofit - The online questionnaire, which was developed to analyze workflows and needs in practical retrofitting processes was closed end of June 2014 and its evaluation started.
  • Press Release: Solar Heating Saves Over 79 Million Tons of CO2 Annually - Gleisdorf, Austria 8 July 2014. The International Energy Agency, Solar Heating and Cooling Programme (IEA SHC) released their latest statistics on worldwide solar heating and cooling. With a growth of 9.4% in 2012, the installed capacity of solar collectors reached 269 GWth. The collectors provided 228 TWh of solar thermal energy, thus saving 79 million tons of CO2 emissions.
